Title: |
|
MIPS first light |
|
|
|
|
|
Objective: |
|
To determine if the MIPS arrays are responding to illumination through the telescope. |
|
|
|
|
|
Description: |
|
Place a bright star in the FOV of each array. Execute the photometry AOT for each array. For the 160 mm array we may |
|
|
|
have to execute the photometry AOT several times (up to 3) with different scan mirror offsets to ensure the source is in the FOV. |
|
|
|
|
|
Place in Schedule: |
|
After dust cover off |
|
|
|
|
|
Required Conditions: |
|
S/C pointing understood to 1' (TBR) and stable to 0.5" in 500 sec (TBR). |
|
|
|
For 24um, the backgrd radiance must be less than 7.0E-9 W/cm2/sr (< 45K). |
|
|
|
For 70um, the backgrd radiance must be less than 3.1E-10 W/cm2/sr (< 17 K). |
|
|
|
For 160um, the backgrd radiance must be less than 2.6E-11 W/cm2/sr (< 8 K). |
|
|
|
Need suitable star in the OPZ. Observable candidates for 70 & 160 mm arrays are e Car and a Boo.
|
|
|
|
Need a fainter star, such as b Leo, for 24 mm.
|
|
Resources: |
|
|
|
|
duration (best estimate) |
5 min for each array x 4 = 20 min |
|
|
real time downlink |
preferably yes, especially for 160 mm
|
|
|
special post event actions |
No |
|
|
|
|
|
Outcome: |
|
|
|
|
description |
|
Photometry maps of stars |
|
can proceed in parallel with other activity |
|
No, dedicated observing |
|
must outcome be confirmed before next event / test /activity |
|
Must be confirmed before further MIPS operations |
|
method of confirmation (sensor TLM, data analysis, etc.) |
|
Data analysis |
|
estimate of data turn around if required for confirmation |
|
< 24 hours |
|
|
|
|
Unique or included in planned uplink or downlink/analysis tool |
|
|
AOTs |
|
|
|
|
Contingency Plan: |
|
Repeat, changing S/C, scan mirror offsets. Use fainter source if necessary. |
